Tidal energy harnesses the moon's pull for electricity

Tidal energy captures the predictable rise and fall of ocean tides, driven by the moon and sun's gravity, to generate clean electricity. Unlike wave power, this renewable source uses tidal currents or water level changes behind dams. It's highly reliable, following the lunar cycle, making it ideal for grid integration. France's La Rance, opened in 1966, proves its longevity, while South Korea's Sihwa Lake is currently the largest, powering 200,000 homes. Though a small fraction of global renewables, its potential is vast, especially in areas like Canada's Bay of Fundy, where tides reach 16 meters.
